模具的机械性能是材料内部组织结构特征的宏观度量,是模具抵抗失效的能力,因此,从模具的工作条件出发,通过机械性能分析,找出造成模具失效的主导因素,确定衡量此种失效抗力的正确判据(强度或韧性),并针对失效抗力的特定要求,选择合适 Mechanical properties of the mold is a macroscopic measure of the internal structure of the material, is the ability of the mold to resist failure, therefore, starting from the working conditions of the mold, through the analysis of mechanical properties to identify the dominant factor causing mold failure, to determine the measure of such failure resistance The correct criteria (strength or toughness), and for the specific requirements of the resistance to failure, choose the right
